Trigonometric Transform Implementation Details

Several aspects of the Intel® oneAPI Math Kernel Library TT interface are platform-specific and language-specific. To promote portability across platforms and ease of use across different languages, Intel® oneAPI Math Kernel Library provides you with the TT language-specific header file to include in your code:

mkl_trig_transforms.h, to be used together with mkl_dfti.h.

Note

Use of the Intel® oneAPI Math Kernel Library TT software without including the above language-specific header files is not supported.
